Synopsis Gusty winds and several degrees of cooling today from
tucson westward with much cooler temperatures east of tucson.

Otherwise, very warm mid-january afternoon temperatures and
generally dry conditions will persist most of the week. A pattern
change this weekend should bring much cooler temperatures and the
chance of valley rain and mountain snow late Friday night into
Saturday.

Discussion Latest IR wv satellite imagery shows considerable
mid high level cloudiness across graham greenlee cochise counties
pushing to the east towards new mexico with mostly clear skies from
tucson westward, though more cloudiness is upstream especially
across southern california. Weak ridging aloft remains in place this
morning with a backdoor cold front now just east of tucson pushing
to the west. This will lead to gusty easterly southeasterly winds
especially across the tucson metro area in the normally
susceptible spots on the south and east sides of town today.

Meanwhile, temperatures will cool slightly from tucson westward
today compared to yesterday but more significant cooling will occur
east of tucson as cooler air advects in from new mexico. High
temperatures for much of graham greenlee cochise counties will be
10 to 15 degrees cooler than yesterday.

The aforementioned weak ridging aloft will break down this evening as
weak shortwave energy shears off from the main trough off the
pacific northwest and moves across northern and eastern arizona.

This system is quite moisture starved with a lack of lower level
moisture. However, we can't rule out a slight chance of rain and
snow showers across the white mountains tonight.

Progressive shortwave ridging will move across the area Thursday
into early Friday ahead of a more significant trough poised to move
in just in time for the weekend. The ridging will result in benign
weather on Thursday with daytime temperatures continuing to warm.

Friday will start the transition with continued mild temperatures
and perhaps a few afternoon breezes.

The 00z model runs continued to slow down the trough this weekend
with a cold front now sweeping across the area on Saturday. This
system will be rather moisture starved given its progressive nature
and trajectory. The biggest change will be the sharply colder
temperatures both Saturday and Sunday with a freeze possible in
tucson especially Sunday morning. Regarding precipitation chances,
there will be a chance of a few valley rain and mountain snow
showers along with the cold front and then due to the trough axis
and instability Saturday and into Saturday evening. QPF amounts will
be rather meager with most locales seeing less than 0.10". A few
inches of snow are possible in the mountains due to enhanced upslope
but this isn't shaping up to be a significant winter storm. A more
zonal westerly flow is expected early next week with temperatures
warming up to about seasonably normal levels on Monday.

Made a few tweaks to the short term sky cover in the forecast update
this morning, otherwise no updates.

Aviation Valid thru 17 18z.

Sct-bkn clouds into Wednesday morning with CIGS briefly down as low
as 12k ft agl. Ely sely sfc wind increasing to 15-20 kts from tucson
eastward this morning. Speeds will decrease late this afternoon into
this evening. Aviation discussion not updated for TAF amendments.

Fire weather A storm system passing north of the area will
create gusty easterly 20-ft winds today, as well as a slight chance
of showers mainly in the white mountains late tonight into
Wednesday. Things will dry out on Thursday before another system
moves through late Friday night through Sunday morning. This
disturbance will result in cooler temperatures, breezy
westerly southwesterly winds and scattered valley rain and mountain
snow showers. Dry conditions and near normal high temperatures
return early next week.

Twc watches warnings advisories None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
